Software vs. hardware raid

IDE RAID Examined
·
· Score: 3, Interesting
A friend of mine set up a raid0 (striped array) using the built-in raid-controller in his motherboard. Later, this motherboard had to be changed. To our great surprise, the raid information was only stored in the motherboard and thus permanently lost. This could be a good thing to know... Make sure the data is not lost if the controller fails.
Personnally, I run several software RAID arrays under Linux and it works very well. It's easy to manage and gives me decent performance on my rather old machine.
I feel very confident in mirroring system/boot partitions on my linux machines =)
One of them, Ralsky's list man, concentrated on finding new names to add to the 250 million e-mail addresses in his database and weeding out canceled accounts.
So... this spammer actually removes canceled email accounts...
Thus if you set up a software like spambuster and configured it to answer "this email address is no longer valid" they would take you of his list right ?
Does this already exist ? Has someone else already thought about it ?
As a student in Computer science, we had to take a class in Intellectual Property.
After buying my own domain (lastname.org), I asked this specific question: "Do I have to worry about someone coming to take away my domain name from me?"
The answer was no. As long as I use it for my own use and do not infringe on today's copyright (if someone registers my lastname as a trademark later, I was first !)
An important question when discussing IP is "who used it first ?" If someone else comes along later saying "this is my name", too bad for them.
BMRT is a free (as in beer) renderer that complies with Pixar's Renderman format. Thus, if you use a modeler that can export in Renderman format, you can use BMRT for rendering. I haven't used it much, but it has been used in several major film productions.
Binaries are available for several platforms, including windows, linux and solaris.
Originally created by former Pixar employee Larry Gritz, BMRT was then integrated into a startup called Exluna that was recently bought by Nvidia. They stopped distributing BMRT, but some online resources are still available.
Now, if you're still interested in trying out the software, it is still available on the web (try searching for "BMRT2.6" using your favorite search engine)
Larry Gritz also wrote a nice book, called "Advanced Renderman", which explains quite a lot about shaders, Renderman and uses BMRT for examples.
If you're interested in finding out more about Renderman, check it out !

In four days, my machine has been contacted by 24 different machines on port 80. By scanning UDP port 2002 on these, I found that 12 of these accept() connections.
Does anyone have a good idea of how to tell these people that their machines are infected ? Most of the addresses contained "adsl" or "cable" indicating UNIX boxes for home use...
My Linux system filters incoming traffic on most ports (including 80 and 443). Looking through the log files, I noticed an increase in the amount of request on port 80 since a few days.
I am not saying that this is necessarily coming from the apache worm, it could also be a spam spider or something else.
But what is more interesting is that I just (10 min ago) had the first requests on port 443.
Could this be the evolution of the first version ?

At least 80% of the traffic from broadband users comes from downloading proprietary files. To stop this would strangle the usage of broadband according to some Tele2 official.
This behavior saves the ISPs (already in trouble) and the music industry should think over their business models. The Music industry has an incorrect pricing and has failed to adapt the new technologies.
I am working on a similar project: to create an international (european languages) dvorak-like layout for programmers or multi-lingual people.
In Europe, there is about one qwerty-type layout for each language or country. Most languages have some special characters (èàéüäö etc). If you want to use characters from another language, it may not be possible or require some special (difficult to remember and different for each layout) sequence.
What I am looking for is direct access to all special characters used by swedish, french, german, italian, spanish and programming languages (èàéäüö[]{}$# etc). Using dvorak as basic layout to build upon.
I will post more on this as soon as I have finished (after summer vacations)
My university is running a research project on "tracking 3D textured object in the presence of aspect changes". Using a computer, a camera and holding a box in your hand, you can animate a light saber.
Here is information about the project and this is an image of the laser sabre in action.
Last summer, we spent a few days upgrading 40 PCs running windows at my university. We changed motherboard, processor, graphics card and added more memory. (same case, harddrive and CDROM)
Start by doing one machine perfectly and then the other's won't be any problem.
Installing was easy as we were already using Ghost.
Your success will probably depend on the ease of installation / maintenance of the new boxes. It's worth spending a lot of time getting it right from the start.
Well, one solution is to use an external antenna which amplifies the signal. I know someone did this with an airport and increased the range by a factor of three.
There is also a special mode to make several access points communicate.
In fact, there are several wireless channels available, so the bridges do not interfere with wireless clients.
Napster never would have gotten so many users and so much publicity if it had not been created to allow the free distribution of copyrighted material.
I know some people argue that "free" music was also exchanged, but this has no or little sense as it could just as well be distributed on a website.
Many websites probably have contributed to mp3's distibuted on the internet. In case this goes through, it would be interesting to see who else goes down the drain.
However, given the difficulty of catching Napster as they pushed the trial further and further away, I would be very surprised if this one got a happier ending...
First of all, I think we all agree that someone's going to crack the time-limited format, so that's not going to stop anything.
Secondly, 500MB is only an option for people with a FAST internet connection, and these people can already download the film once someone has made a DIVX of the DVD version...

So

Does this already exist ? Has someone else already thought about it ?
... if they would have put a standard LCD screen so that you could add your own skins or display nice things on it.
It's a little boring only having a template for the buttons.
But I guess that's not very far away, soon some company will put out something similar on the market.
/lastname/ is of course supposed to be replaced by my real family name which I don't find any interest in putting out here.

As Steve mentioned, "Rendez-vous" (zero configuration network) has been proposed as a IETF standard.
Here are some links from their website:

Here is a movie (37Mb) showing it in action.
Now, all you have to do is to buy the handle from parksabers.com to get the real feeling

... Everytime he made an experiment it exploded.
;-)
My favorite "kitchen experiment" is igniting a mix of flour and air to show that any powder being relatively explosive (very fun not to try at home)
But the most violent explosion was mixing H2 and Cl2 and igniting with a laser beam (really NOT try at home, explodes at light exposure
Well, as the Concordes are currently grounded, they probably wouldn't notice anything ;-)
"I'll just borrow it for a little while, OK ?"
Rent a Concorde and fill it with a lot of explosives. It's that easy ...
Well, one solution is to use an external antenna which amplifies the signal. I know someone did this with an airport and increased the range by a factor of three.
There is also a special mode to make several access points communicate.
In fact, there are several wireless channels available, so the bridges do not interfere with wireless clients.
"Using higher-gain antennas than the ones shipped with the WAP11 ..."
That's a nice feature, but it is not mentioned in the article.
Who knows more about this ?
Napster never would have gotten so many users and so much publicity if it had not been created to allow the free distribution of copyrighted material.
...
I know some people argue that "free" music was also exchanged, but this has no or little sense as it could just as well be distributed on a website.
Many websites probably have contributed to mp3's distibuted on the internet. In case this goes through, it would be interesting to see who else goes down the drain.
However, given the difficulty of catching Napster as they pushed the trial further and further away, I would be very surprised if this one got a happier ending
From the statement: One must "Have unobstructed view of one of our transmitter locations"
...
;-)
Wonder what kind of technology that is
Given that 802.11 only reaches about a 100-300 meters with an open view, they probably need MANY access points
The article only says it will be compatible with
...
Windows 95, 98, ME, and 2000 Professional. What about all other operating systems supporting 802.11 ?
I'm sure people with a Titanium, iBook, Linux or BSD laptop would like to join in too
First of all, I think we all agree that someone's going to crack the time-limited format, so that's not going to stop anything.
...
Secondly, 500MB is only an option for people with a FAST internet connection, and these people can already download the film once someone has made a DIVX of the DVD version
